CVE-2025-23536 Overview
CVE-2025-23536 is a reflected Cross-Site Scripting (XSS) vulnerability in the Track Page Scroll WordPress plugin by mndpsingh287. The flaw affects all versions up to and including 1.0.2. The plugin fails to properly neutralize user-supplied input during web page generation, allowing attackers to inject arbitrary JavaScript that executes in a victim's browser.
The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). Exploitation requires user interaction, typically through a crafted link, but no authentication is needed.
Critical Impact
Successful exploitation enables session hijacking, credential theft, and unauthorized actions performed in the context of the targeted WordPress user, including administrators.
Affected Products
- mndpsingh287 Track Page Scroll plugin for WordPress
- All versions from initial release through 1.0.2
- WordPress sites with the vulnerable plugin installed and active

Technical Details for CVE-2025-23536
Vulnerability Analysis
The Track Page Scroll plugin processes user-controllable input and renders it back into the response without sufficient output encoding or input sanitization. An attacker who tricks an authenticated WordPress user into clicking a crafted URL can deliver malicious JavaScript that executes in the victim's browser session.
Because the issue is reflected and triggered through the network, exploitation typically uses phishing or social engineering. The scope changes when the injected script accesses resources outside the vulnerable component, and the payload runs with the privileges of the targeted user. If the victim is an administrator, the attacker can pivot to plugin installation, account takeover, or persistent backdoor placement.
EPSS data places the probability of exploitation at 0.232% (percentile 45.847) as of 2026-05-04, indicating low but non-trivial real-world interest.
Root Cause
The root cause is missing or inadequate sanitization of request parameters that flow into HTML output. The plugin echoes attacker-controlled values into the page without escaping characters such as <, >, and ", allowing the browser to interpret injected content as executable script.
Attack Vector
The attack vector is network-based with required user interaction. An attacker crafts a URL containing a malicious payload in a vulnerable parameter handled by the plugin. When the victim visits the link on a site running Track Page Scroll <= 1.0.2, the server reflects the payload into the response, and the browser executes the script in the site's origin.

Detection Methods for CVE-2025-23536
Indicators of Compromise
- HTTP requests to WordPress endpoints associated with the Track Page Scroll plugin containing <script>, javascript:, onerror=, or encoded variants in query parameters.
- Outbound browser requests to attacker-controlled domains following visits to plugin-handled URLs.
- Unexpected creation of administrative WordPress accounts or modification of user roles after a user clicks an external link.
Detection Strategies
- Inspect web server access logs for query strings containing HTML or JavaScript syntax targeting plugin parameters.
- Deploy a Web Application Firewall (WAF) rule set with reflected XSS signatures aligned to OWASP CRS.
- Monitor for anomalous Referer headers and short-lived sessions originating from external link clicks into WordPress admin pages.
Monitoring Recommendations
- Enable verbose access logging on the WordPress front-end and forward logs to a central analytics platform for query-string analysis.
- Alert on responses that reflect raw <script> tags or event handler attributes back to clients.
- Track plugin inventory across WordPress fleets and flag installations of track-page-scroll at versions <= 1.0.2.
How to Mitigate CVE-2025-23536
Immediate Actions Required
- Identify all WordPress sites running the Track Page Scroll plugin and confirm the installed version.
- Deactivate and remove the plugin if a patched version is not available or the plugin is no longer needed.
- Force a password reset and invalidate active sessions for administrators who may have clicked suspicious links.
Patch Information
At the time of publication, the vendor advisory tracked by Patchstack lists Track Page Scroll versions through 1.0.2 as affected with no fixed version identified. Site operators should monitor the Patchstack advisory and the WordPress plugin repository for an updated release.
Workarounds
- Uninstall the Track Page Scroll plugin until a patched version is published.
- Deploy a WAF rule that blocks reflected XSS payloads against the plugin's request paths and parameters.
- Apply a strict Content Security Policy (CSP) that disallows inline scripts and restricts script sources to trusted origins.
- Train administrators to avoid clicking unsolicited links to their own WordPress sites.
# Configuration example: Apache mod_security rule to block common reflected XSS payloads
SecRule ARGS "@rx (?i)(<script|javascript:|onerror=|onload=)" \
"id:1002536,phase:2,deny,status:403,msg:'Blocked reflected XSS attempt (CVE-2025-23536)'"
